Many people i see are having problems installing but none were similar to my issue. I have a computer that works fine but has no OS as of now. I bought a new hard drive for it and i just bought windows 7 FULL (not upgrade) but it will not boot/install when i insert disc. I have the drive set to boot first and everything is in full working order since POST is fine and i see the black and white menu that always comes up before windows starts... When i insert the windows 7 disc and press enter, after a short while it says that it failed to boot and that i should insert system disc...i have no idea what to do now, any help would be great seeing as i have few options left. Thanks.
